Abstract (en)

[origin: WO2015114069A1] The invention is directed to a process for the biological conversion of bisulphide into elemental sulphur, comprising the following steps: a) converting bisulphide as dissolved in an aqueous solution to elemental sulphur in the presence of sulphide-oxidising bacteria and under anaerobic conditions to obtain a first liquid effluent comprising elemental sulphur and used sulphide-oxidising bacteria; b) regenerating the used sulphide-oxidising bacteria as obtained in step (a) and as comprised in an aqueous solution in the presence of an oxidant to obtain a second liquid effluent comprising regenerated sulphide-oxidising bacteria; c) separating elemental sulphur from either the first and/or the second liquid effluent; d) using the regenerated sulphide-oxidising bacteria in step (a) as the sulphide-oxidising bacteria.
